SPECIFICATION forming part of Letters Patent No. 726,552, dated April 28, 1903. Application filed September 22, 1902. Serial No. 124,398. (No model.)

To aZZ whom, it may concern.-

Be it known that 1, WILLIAM LoUDEN, a citizen of the United States, residing at Fairfield, in the county of Jefferson and State of Iowa, have invented a new and useful Improvement'in Hay-Carriers, of which the following is a specification.

My invention consists of certain improvements in hay-carriers, which are hereinafter described and which are specifically set forth in the claims.

In the accompanying drawings, forming a part of this specification, Figure 1 is a perspective ofa hay-carrier embodying my invention. Figs. 2, 3, and 4 are enlarged vertical sections on lines of corresponding numbers in Fig. 1. of the carrier-stop. Fig. 6 is a perspective of the locking-dog. Fig. 7 is an enlarged horizontal section on the line 7 7 of Fig. 6, adjacent edges of the carrier-frame being also shown and broken away.

Referring to the drawings,A represents the trackway; B, the carrier mounted therein; 0, the carrier-stop applied to the trackway, and D suspending-hooks for holding the trackway in elevated position. The trackway consists of a sheet of metal bent so as to form a rectangular-shaped tube having an opening longitudinally through thecentral portion of its lower side, with inwardly and upwardly turned edges E. The parts F form the treadways for the wheels W of the carrier to run upon.

Grepresents the upper frame of the carrier, which is preferably made in two pieces provided with arms adapted to pass up through the opening between the upturned edges E.

and carrying the wheels W. The hooks D have their lower ends headed and are passed through holes in the upper sides of clips H, which are made to conform to'the contour of the trackway A, so as to be adjustable thereon and to permit the hooks D to be connected to overhead supports at any desired point along the trackway.

The carrier-stop O is made in two pieces and is adapted to clamp on the outside of the trackway A. Each piece is provided with an arched portion I, which is inwardly inclined, so as to meet together at the top, and at this point the pieces are secured together Fig. 5 is an inside view'of one side by a bolt or rivet J. Immediately above the 'tracklway A each piece has perforations through which bolts K are passed and which when drawn up tight serve to clamp the pieces 0 firmly on the trackway A. The upper ends of the pieces 0 are extended sufficiently above the trackway A to brace themselves against each other and when drawn together with the bolts K to clamp tightly upon it. By this means the stop may be firmly clamped upon any desired part of the trackway and be readily adjusted thereon. The lower ends of the pieces 0, composing the stop, are fitted with the usual inclined lock-lifting flanges L and retaining-lugs M, and the upperportion of the carrier-frame G is adapted to pass between them. The lower portion of the carrier is provided with the usual rope-wheels N, forkpulley O, and grappling-hooks P and is preferably swiveled to the upper frame, as shown in the drawings. In the central part of the upper frame is mounted, so as to have vertical movement therein, a locking-dog R, having a circular base S,which engages the grapplinghooks P in the usual manner. The upper arms of this dog are inwardly contracted, so as to pass between the flanges L and lugs M of the stop-pieces C, and are fitted with outwardly-projecting lugs T, which are adapted to slide up the inclined flanges L, so as to lift thecircular base S from between the grappling-hooks P and to catch against the retaining-lugs M, all in the usual manner. Between the upper ends of the armsof the dog R is mounted a grooved wheel U, which is adapted to run up and down in a slot V in the central part of the upper frame of the carrier. The upper ends of the dog R are held in'place laterally by means of the groove in the wheel U, running on the edges of the carrier-frame G, adjoining the slot V, as shown in Figs. 1 and 2. The wheel U is mounted on a bolt or rivet Y, which is passed through the lugs T. This central support of the upper end of the dog R permits it to pass between stop-pieces O and to engage the flanges and lugs on the inner sides thereof.

When the lugs T slide up the flanges L, the circular base S is lifted from between the upper ends of the grappling-hooks P, which permits them to turn on their pivots and release the fork-pulley 0. The base of the dog R,

now resting on the upper ends of the hooks P, will hold the dog in elevated position, so the lugs T will be held in contact with the lugs M, which will hold the carrier stationary in the trackway A.

When the fork-pulley is drawn up in contact With the central arms of the hooks P, it' will cause them to turn again on their pivots and allow the dog R to drop between them, thus releasing the dog from the stoppieces 0 and permitting the carrier to run in the trackway and at the same time looking the fork-pulley O in the grappling-hooks P.

What I claim is 1. In hay carriers, a trackway having flanges on its interior sides, a carrierprovided with a lock mechanism and having wheels adapted to run on said flanges, and a stopping device applied to the exterior sides of said trackway and adapted to coact with said lock mechanism.

2. In hay-carriers, a tubular-shaped track- Way having a continuous slot in its .lower side, and a treadway adjacent said slot, a carriage adapted to pass through said slot and run on said treadway, a stepping device secured to the outer side of said trackway and a lock mechanism in the carrier adapted to cooperate with said stopping device.

3. In hay-carriers, a tubular-shaped trackway having a continuous slot in the central part of its lower side, a treadway adjoining each side of said slot, a carriage adapted to pass through said slot and run on said treadways, a stopping device having two wings to embrace opposite sides of the trackway, and a lock mechanism adapted to cooperate with each of said wings below said trackway.

4. In hay carriers of the character described, a stopping device composed of two parts adapted to embrace the trackway between them, the upper ends of said pieces being extended up above the trackway so asto brace each other, bolts immediately above the trackway to clamp the pieces thereon, and the lower ends of said pieces projecting below the trackway on each side and adapted to cooperate with the lock mechanism of the carrier.

5. In hay carriers of the character described, a locking-dog having vertical movement in the frame of the carrier, its lower end adapted to cooperate with one or more grappling-hooks and its upper end to cooperate with a stopping device, the upper end of said dog being fitted with a grooved wheel to run in the carrier-frame and hold said upper end in position.

6. In hay carriers of the character described, a locking-dog having vertical movement in the carrier-frame,its lower end adapted to cooperate with one or more grapplinghooks, a grooved wheel between its upper ends, a slot in the carrierframe for said wheel to run in, a stopping device applied to the outer sides of the trackway and extending below it on both sides, and outwardlyeextending lugs on the upper ends of the dog to cooperate with said stopping device.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

WILLIAM LOUDEN.
